Question

Solve the equation A=1/2 bh for b.

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given equation

`A=(1)/(2)bh`

STEP 2: Multiply through by 2

`\begin{gathered} 2\cdot A=2\cdot(1)/(2)\cdot b\cdot h \\ 2A=bh \end{gathered}`

STEP 3: Divide both sides by b

`\begin{gathered} (2A)/(h)=(bh)/(h) \\ b=(2A)/(h) \end{gathered}`

Hence, the value of b can be gotten by the equation:

`(2A)/(h)`
